What do you like best?
Easy to use, anyone who I've sent a file has had no issues receiving and downloading. Some of them have told me they've gone on to use the product regularly themselves.
What do you dislike?
Nothing to do with pdffiller, but I sometimes forget to set up the files I'm uploading in the right folders. That's on me.
What problems are you solving with the product? What benefits have you realized?
Under the 'documents' tab, the 2 columns on the right could be made more distinctly different from each other to denote they are in fact different. They are just two shades of gray and not that different in tone.

What do you like best?
In-line text, change font size, save options to name a few. Being able to quickly fill out insurance applications and having the text line up is amazing. I have been looking for this feature for awhile. PDFfiller is quick, easy, and has boosted my efficiency greatly.
What do you dislike?
The page fails when resizing text, and then you need to reload it. That is really my only issue other than when saving a PDF to my local machine, I don't need the indicator to pop up and tell me where to look.
